Y V'lihis invention relat'esmore vspecifically toV Vtravelling concrete vmoldV forms utilized in the erection ofvv concrete buildingwallmvthe forms being constructed so as to-render possible the attachment to the wall surfaces during the .pouring operation, ofA tie rods,

` bolts, and structural beainawithout interfering with the movementvof the forms.

it is often desirable to insert and anchor at intervals during the .erection of the walls metal studs projecting from the faces'of the walls to facilitate' the ready attachment thereto of wood beams,l for the purpose of attaching wooden metal structures `to the- VVVwalls.

included in lconcrete structures, as well as licor slab tie rods, such constructions proa jecting fromthe wall faces andvinterfering Further steel beams arefrequently with themovement lof the travelling mold forms. By'means of the mold form construction hereinafter specifically described.,V

an elevating mechanism 19 is provided, said v v mechanism being'substantially the; same as Y shown in the'NVaugh patent heretofore referred to.y Y

Assieme bousjmuue fads,beamatefj that are secured toV the concrete wallsvand` poured, it vvbecomes necessary. to 'provide a vproject beyondA their faces as `the same are 4 and also arranging the formsin order that@A they may be constantly moved upwardly as i v the pouring of the walls progressesv without 'interference' `from the l projecting objects.v

In the accomplishment ofthis object the `wall -A-- of the mold forms 'is provided with a plurality.v of vertically disposed slots L should double vertical rows ,of threaded studs 21y be needed for attaching wood beams l f p to the faceof the wall in the formation of Fig. 6 is a like view showing the third interior structures,fsuch as elevators andthe like, thel channel beams 17 on the outer face of the wall are cut the required length'.` so

that thel adjacent ends of theb'eams at ithel slots 2O overlap the sameslightly(SeelrgV 3), .and ,iirorderto connect theiinold'vwall i' lengths `tegether a. plurality of 4shortverti-- cally disposed channel beams22` are bolted` 11ol `tothe beamsv 17, af pair on each side ofthev slots. Bolted'orfotherwise secured `to these y last named channel beams are a vplurality of-` Vhorizontally'disposed short channel beams,V

here shown as three in number and designated by numerals 23, 24 and 25. By means of the foregoing construetion sufficient space in Jront of the slots in the mold Wall'tvill,

Y be provided for the projecting ends of the threaded studs 21, andfas :a consequence the studs vWill not interfere Withthe upward movements of the mold forms.

Each rovi7 of the threaded stud boltslare if vspaced a distance apart,land in order to hold i the same in position with respect to the movable torms during the Wall pouring operation the same are mounted on closureboards 27, that are disposed in the slots v.20 ofV the mold walls, the ends of thev channel beams .i717 bearing against thevertical edges of the n Walls are poured.

Vboards andfinaintaining them in position,

the boards also serving to prevent 'concrete from liowing through the iva-ll'slots-,as the `YVhen itis desired to-attach floor slab metal. rods '30 to the building Wall, the

method of' operating the travelling mold 'forms is substantially the samewvith the eX- ceptionthat f the channel `bars 23, 24, and

i* 25, haveto be removed and replaced at intervals during theupi'vard movement o'f the` forms as the rods 'BO'are of agreater length' Y ythan the threaded stud bolts.

Y `The meth-od ofinsertingthe ioorslab 28 the rods in position is best' illustrated in the four diagrammatic views of the drawing,

Y Figs. 4 to 8 inclusive. Invlig. 4 isillustrated the iirst step in securingv or anchoring the metal/rods in the building Wall. The tie rods are supported prior to the'embedment of, their'ends in the Wall by means of removable closure boards 31, 32, Which are mountedin theY slots 2O oi the Wall -A- of the mold forms, the Vadjacent ends of the channel bea'ms 17 holding Vthesame in position "between the vertical facesof` the Wall. The

'outer' ends ofthe tierods be secured against sagging prior'to the embedment of y their yinner ends in the'Wall structure by r Wires, or other suitable securing means (not shown).

When the forms '-v-A reach the position as shown in Fig. 5r the uppermost channel beam 25 isremoved permitting the forms to pass theirods 30.v 'In Fig. 6 the beam 25 has been replaced and beam 24 removed, the beams beingremoved and replaced in order as the forms progress upwardly.v V/Vlien the i'oriiis'reach the position shoWnfinFig. 6, the

closure board l31', is removed'from lthe posi# tionshowiirin Fig. 5 and yreplaced above the Y board 32 as'shown in Fig. 6. After the con'- Y crete of the Wallhas set sufciently the boards carrying the tiey rods `and stud bolts may be removed in any convenient manner.

, 7D Themaiiner ofsecuring structuralI beams 35Y in position between tivo concretewalls 36, 3,7, is illustrated linFigs. 9 to l2 inclusive. In this construction'the concrete mold `forms -A. as Well as the bracing and reinforcing consists of timbering, boltedtogether in sub-l stantially the same manner as the metal'conf-v` structed forms.

The linner mold walls 3810i the forms Ar-i are each provided Wi'tli'a Vvertical slot 89 similar in formr to the slots -oimed in i the .mold Walls ofthe metal molds, and

closure boards 40, 4l, arelprovided similar to the'boards of kthe first forms. Aform horizontally disposed timbers 42, 43

In this are bolted to 'the outer faces `of mold C Walls 38, their oppositely disposed ends overlapping th'e slots 39 for the purpose of holdl ing the boards 40, 41,7in positionrduring the movement ot the forms. Bolted to the outer.v

faces of these timbers, are v vertically 'dis-f c posed timbers 44, a pair `on each side ofthe Y slots 39. ,-Boited to the vouter races otthese timbers 44 are shorthorizontally disposed y bars 45,-adapted unctionin thek same man!"` neras the channel irons 23, 24, 25,0f the tirst describedA form.

In embedding the lends of the VI beam inV the tivo Walls 36, 37, vthe beam vis suspended between the Walls inthe desired position byV a crane not shown) the ends of thebeani extending through the vertical slots 39 in ino mold form Walls and terminating mid-'Way y Y the tliicknessof the Walls. As the oppositely disposed ends-of the closure'boards 40, 4l', engage the` beam ianges when placed in position provision must be made' to close; the

openings at either side of the vertical beam web to prevent the -vvet concrete from l'low.` ing from the mold cavities of the Wall when the same are poured. To this end'closures 4T are provided, each closure consisting lof a pair transversely disposed Wood closure plates 48 that lill the spacesbetween theA beam lianges. Secured tothe outer vertical edges of theseclosure plates in any suitable inany Y ner arev vertically disposediiat plates 49 eX- tending the height of the beam, and held in position' by horizontally disposed bars 50 f nailed thereto. Eachclosure is 'of the lsame f Width as the'verticalV slotsl 39 ofthe mold Walls in which they are disposed,` and it Will be clear .Y that they will Vform an eiective closure around the ends of the'`- beams and Y prevent concrete vfrom iowing outwardly from -the Wall f molds.

' During thepouring of the building Walls i i 36,37, the closure boards areinserted inithe slots 39 of the inner Wallsofthe mold forms and move upwardly therewith. When the upp'erccross4 bars 45 of the forms are ldirectly underneath the beam the saine are removed to permit the passage of the forms thereby, replaced after said passage, and the upper closure boards al are then inserted in the slots. When the lower-,bars 45 reaches l the under face ofthe beams the same isalso f removed to permit passage ofthe forms, and

then replaced like the first bar. Y Y

The inner ends of the beam web at their points of embedinents in the VWalle are provided With holes, for-the passage therethrough oit' Wall reinforcing'rods 51. j

By means of the above described mold'v i form mechanism the floor'tie rods, studs,v and vbeams of a concrete building may bev Aeasily inserted in place-in the 'building Walls v Without interfering With the movementproi' the forms.
